Dowel pin for MAK 16M453AK

The dowel pin, part number 1.2810-56, is a precision component used in the MAK 16M453AK engine. Its primary function is to establish and maintain exact alignment between two or more mating mechanical parts. Unlike fasteners intended for clamping, this pin is inserted into corresponding holes to prevent lateral or rotational movement, thereby preserving the geometric integrity of the assembly.

This component is specifically engineered for the MAK 16M453AK engine, which is utilized in marine, power generation, and heavy machinery applications. In such complex engine systems, the precise positioning of components like the engine block, cylinder head, main bearing caps, and gear housings is necessary for smooth operation and uniform load distribution. The pin ensures these parts are positioned correctly to prevent internal stresses.

Dowel pins serve as locating elements in mechanical assemblies. By providing a tight fit within the assembly holes, they eliminate clearance and ensure that parts remain centered under operational loads. Proper alignment is essential to prevent premature wear on bearings, seals, and other moving parts, as well as to minimize vibration during engine operation.
